A still from a security camera during an armed robbery at Norton Mini Mart, 3381 McCracken, Saturday about 7 p.m.

The suspect in the 7 p.m. Saturday robbery at the Norton Mini Mart, 3381 McCracken, remained at large early Monday.

The suspect is described as a white man in his late 20s, about 5 feet 8 inches tall, medium build, who was wearing a black winter coat and a black ski mask during the incident, said Norton Shores Police Lt. Jon Gale.

Gale said the man walked into the store, jumped over the counter and held a knife to the 22-year-old clerk's chest before grabbing handfuls of cash and fleeing south out of the store's front door.

The man then fled west on Norton Avenue, where Gale said he likely got into a vehicle.
